IE 8, Silverlight 3 on tap for Microsoft's Mix

The expected release of Internet Explorer 8 is likely to be the biggest headline out of Microsoft's Mix conference this week, though the company is likely to spend at least as much time talking about Silverlight 3, the next version of its would-be rival to Adobe's Flash.

Microsoft has already released a near-final release candidate version of IE 8 and is widely expected to declare the browser done as it prepares to address a crowd of Web developers in Las Vegas starting on Wednesday. Microsoft used last year's Mix event to offer the first public demo of IE 8.
